What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeImmune thrombocytopenia (ITP) rarely presents intraoperatively during spinal surgery. We report a case of de novo ITP that first manifested as severe, uncontrolled bleeding during lumbar spinal fusion despite normal preoperative platelet count and coagulation tests.
methodsThe clinical course, perioperative laboratory findings, diagnostic workup, and treatment follow-up of an elderly woman who developed acute severe thrombocytopenia during L2-5 posterior lumbar interbody fusion were reviewed.
resultsAn 81-year-old woman underwent L2-5 posterior lumbar interbody fusion for degenerative lumbar spondylolisthesis. Preoperative platelet count and coagulation parameters were normal. During intervertebral procedures, diffuse oozing bleeding progressively increased without apparent arterial injury, and intraoperative coagulation tests remained unremarkable. On postoperative day 1, the platelet count decreased to 1,000/µL and showed minimal response to platelet transfusion. After exclusion of other causes, de novo ITP was diagnosed. Intravenous immunoglobulin and corticosteroids were insufficient, but platelet recovery occurred after thrombopoietin receptor agonist therapy. Systemic bleeding manifestations included alveolar hemorrhage, purpura, and hematuria. No recurrence of ITP was observed at 1 year.
conclusionAcute ITP should be considered when unexplained diffuse intraoperative bleeding occurs during spinal surgery despite normal coagulation tests. Early reassessment of platelet counts and hematology consultation may facilitate timely diagnosis and treatment.
